I moved from California to Florida and decided that with all the storms in the south that I needed a generator. I looked around and had talked to several supplier for the generator. After to talking to the people at Tech Services Specialties, Inc I decided to go with them . They were prompt and very professional. They did everything that they said they would do and then some. Not knowing when I would ever use the unit, it was still very comforting to know that it was there. About a week after it was installed on a clear sunny day the power went out. Within a few seconds I hear the unit start up and and a few more seconds the power was back on. I thought to myself, now that is cool. About an hour later I came to realize that the unit was still running and I thought the power could not still be out, but when I check with my neighbors it was indeed still out. Well the power was out for almost 4 hrs on a beautiful but hot Florida day. I stayed cool with the generator. I am so glad that I had put the unit in and grateful for the professional job that was done and the great product that the Generac generator is. J. Zell, Fla
